The suburban shift toward the Democrats helps explain why they're about to take control of the House. The graphic below shows the shift — and it shows that even the deep-red rural districts elected Republicans with smaller margins than in 2016.

Why it matters: Races tend to be much closer in the suburbs, and that's where Democrats picked up the most seats. With few exceptions, Democrats in conventionally blue districts won by larger margins than Clinton in 2016 and Republicans won by slimmer margins than Trump in 2016.

How to read this chart: A CityLab data project categorized every U.S. House district by the density of its neighborhoods. By comparing the margin victory for Hillary Clinton or Donald Trump in 2016 to the vote margin in the 2018 midterms, we can see which districts shifted to the left or right by comparison.

  • Districts with higher Democratic or lower Republican margins point left; those with smaller Democratic or higher Republican margins point right. The color of each arrow shows who won the district in 2018.

Elevator anxiety will stifle reopenings

Will you step back into an elevator any time soon?

Why it matters: Tens of billions of dollars — and the future of cities around the country — rest on the answer to that question. So long as workers remain unwilling to take elevators, hundreds of billions of dollars' worth of office real estate will continue to go largely unused.

Brazil coronavirus death toll tops 100,000 and case numbers surpass 3 million

Brazilian President Jair Bolsonaro posted a photo of himself to Facebook congratulating his soccer team, Palmeiras, for winning the state title Saturday, moments after the health ministry confirmed the national COVID-19 death toll had surpassed 100,000.

Why it matters: Brazil is only the second country to confirm more than 100,000 deaths from the coronavirus. On Sunday morning, it became the second country to surpass 3 million cases, per Johns Hopkins. Only the U.S. has reported more. Bolsonaro has yet to address the milestones. He has previously tested positive for COVID-19 three times, but he's downplayed the impact of the virus, which has crippled Brazil's economy.
